Review Detail of Narconia in Even Though I was Peasant, Now I'm a Demon Lord

It's a great book, but has 1 major issue. After chapter 140 something some chapters start to repeat just with different titles if I remember correctly. So the last 20ish chapters were partially confusing and partially useless repeats. I wish they would be fixed, feels like a waste of coins unlocking them sin e they are repeats.
